38 /* This structure maintains information on a per-objfile basis about the
39 "entry point" of the objfile, and the scope within which the entry point
40 exists. It is possible that gdb will see more than one objfile that is
41 executable, each with its own entry point.
43 For example, for dynamically linked executables in SVR4, the dynamic linker
44 code is contained within the shared C library, which is actually executable
45 and is run by the kernel first when an exec is done of a user executable
46 that is dynamically linked. The dynamic linker within the shared C library
47 then maps in the various program segments in the user executable and jumps
48 to the user executable's recorded entry point, as if the call had been made
49 directly by the kernel.
51 The traditional gdb method of using this info was to use the
52 recorded entry point to set the entry-file's lowpc and highpc from
53 the debugging information, where these values are the starting
54 address (inclusive) and ending address (exclusive) of the
55 instruction space in the executable which correspond to the
56 "startup file", i.e. crt0.o in most cases. This file is assumed to
57 be a startup file and frames with pc's inside it are treated as
58 nonexistent. Setting these variables is necessary so that
59 backtraces do not fly off the bottom of the stack.
61 NOTE: cagney/2003-09-09: It turns out that this "traditional"
62 method doesn't work. Corinna writes: ``It turns out that the call
63 to test for "inside entry file" destroys a meaningful backtrace
64 under some conditions. E.g. the backtrace tests in the asm-source
65 testcase are broken for some targets. In this test the functions
66 are all implemented as part of one file and the testcase is not
67 necessarily linked with a start file (depending on the target).
68 What happens is, that the first frame is printed normaly and
69 following frames are treated as being inside the enttry file then.
70 This way, only the #0 frame is printed in the backtrace output.''
71 Ref "frame.c" "NOTE: vinschen/2003-04-01".
73 Gdb also supports an alternate method to avoid running off the bottom
76 There are two frames that are "special", the frame for the function
77 containing the process entry point, since it has no predecessor frame,
78 and the frame for the function containing the user code entry point
79 (the main() function), since all the predecessor frames are for the
80 process startup code. Since we have no guarantee that the linked
81 in startup modules have any debugging information that gdb can use,
82 we need to avoid following frame pointers back into frames that might
83 have been built in the startup code, as we might get hopelessly
84 confused. However, we almost always have debugging information
87 These variables are used to save the range of PC values which are
88 valid within the main() function and within the function containing
89 the process entry point. If we always consider the frame for
90 main() as the outermost frame when debugging user code, and the
91 frame for the process entry point function as the outermost frame
92 when debugging startup code, then all we have to do is have
93 DEPRECATED_FRAME_CHAIN_VALID return false whenever a frame's
94 current PC is within the range specified by these variables. In
95 essence, we set "ceilings" in the frame chain beyond which we will
96 not proceed when following the frame chain back up the stack.
98 A nice side effect is that we can still debug startup code without
99 running off the end of the frame chain, assuming that we have usable
100 debugging information in the startup modules, and if we choose to not
101 use the block at main, or can't find it for some reason, everything
102 still works as before. And if we have no startup code debugging
103 information but we do have usable information for main(), backtraces
104 from user code don't go wandering off into the startup code. */

666 expressions, such as if the inner loop has reached its end, so
